“No, it won’t,” grumbled Dyke; “there’ll be hot horses under you, then.”

“Yes, but cool air rushing by you. Come, old lad, don’t sham idleness.”

“It isn’t sham,” said Dyke. “I don’t think I used to be idle, but this hot sun has stewed all the spirit out of me.”

Joe said nothing, but led the way round to the back of the long low house, to where a high thick hedge of thorns shut in a lean-to shed thatched with mealie leaves and stalks; these, the dry remains of a load of Indian corn, being laid on heavily, so as to form a good shelter for the horses, haltered to a rough manger beneath.

As Dyke approached, he raised a metal whistle which hung from his neck by a leather thong, and blew loudly. A low whinny answered the call, and a big, raw-boned, powerful horse and a handsome, well-bred cob were unhaltered, to turn and stand patiently enough to be bridled and saddled, afterwards following out their masters like dogs.

And now as they passed the end of the stable, all the languor and lassitude passed away from Dyke on the instant. For he now caught sight of their Kaffir servant lying fast asleep just beneath the eaves of the corrugated iron roof.

The sand hushed the horses’ hoofs, and the Kaffir slept on, with the flies buzzing about his half-open mouth, as if they mistook the thick red lips for the petals of some huge flower.

“I’m not going to stand that,” said the boy.

“What are you going to do?”

“You’ll see,” whispered Dyke. “If I’m to be toiling after goblins, he’s not going to sleep there like a black pig. Go on a little way and look back.”
